A device according to one disclosed embodiment comprises: a control part which determines at least one target frequency of an MRI noise signal generated in an MRI device and generates a control signal for the determined target frequency; and an output part which outputs the control signal, wherein the target frequency is the frequency of the MRI noise signal to be controlled and the control signal is a signal in which at least one of the size and the phase of the MRI noise signal is changed.

Method and device for controlling MRI noise

Provided is a medical image processing apparatus and method. The medical image processing apparatus includes: an image processor configured to extract a blood vessel area and at least one contour line of the blood vessel area from a first image representing the blood vessel area, and to obtain a second image representing an area of at least one plaque based on the blood vessel area and the at least one contour line; a display configured to display the second image; and a user interface configured to receive a user input for correcting at least one contour line corresponding to at least one of the at least one plaque represented in the second image, wherein the image processor corrects the second image based on the user input. The medical image processing apparatus may precisely visualize a contour line of the blood vessel area.

Apparatus and method of processing medical image

An apparatus and a method of processing a medical image are provided. The apparatus is configured to generate a cross-sectional image of an object by transmitting X-rays through a region of the object, and includes an X-ray generator configured to generate the X-rays. The apparatus further includes a controller configured to determine sub-regions included in the region, based on positions of body parts included in the region, determine image qualities of the sub-regions based on types of the body parts included in the sub-regions, control doses of the X-rays based on the image qualities, and control the X-ray generator to transmit the controlled X-rays to the region.

An audio apparatus is provided. The audio apparatus includes an input configured to receive an audio signal containing noise; a period estimation unit configured to estimate a period of a noise pattern in the audio signal; a noise reducer configured to subtract and remove the noise pattern from the audio signal in a frequency domain by using the estimated period of the noise pattern; a noise updater configured to update the noise pattern according to a change in amplitude of the noise; and an output configured to output the audio signal obtained by removing the noise pattern.

Apparatus and method of reducing noise and audio playing apparatus with non-magnet speaker

A tomography apparatus includes a data acquirer configured to obtain a first partial image and a second partial image of an object based on data that is obtained respectively at a first angular section corresponding to a first time and at a second angular section corresponding to a second time during a tomography scan of the object that is moving, a controller configured to determine first information indicating a motion amount of the object in a first area of an entire image based on the first partial image and the second partial image, and determine second information indicating a degree of blur of a point included in the object in the first area based on the first information, and an image processor configured to correct the first area based on the first information and the second information, and output a tomography image based on the corrected first area.
